1 Claim.

particular manner of disposing the barrier. on

the implement.

With these and other objects in view thi invention resides in certainnovel features of construction and arrangement of elements to behereinafter set forth in the specification, illustrated in theaccompanying drawings and pointed out in the appended claim and, whilethis disclosure depicts my present conception of the invention,

the right is reserved to resort to such change in construction andarrangement of elements as come within the spirit of the invention.

In the accompanying drawings forming a part of this invention:

Fig. 1 is a plan view of the barrier setting up implement.

Fig. 2 is a side view thereof.

Fig. 3 is a vertical sectional view through the barrier and supportingelementsthereof.

Fig. 4 is a detail sectional view through a portion of a planted fieldshowing the barrier set up in operative position therein.

In the present illustration of this invention the numeral 5 designates,in general, a barrier carrying and setting up implement consisting of abeam 6 having a plow share I secured to its forward end, to form afurrow in the ground.

Suitably spaced to the rear of the plow share and secured to the beamGare cover blades 8 extending diagonally forward with their outer endsterminating beyond the longitudinal path traversed by the plow share soas to push the loose dirt plowed up by said plow share inwardly'where itwill pass through a space between the inner ends of said blades for apurpose to be hereinafter set forth.

Journalled on said beam 6 rearwardly of the aforesaid blades are opposedground packing wheels 9.

or other suitable means capable of performing a similar function.

In order to permit the roll of paper to unwind evenly and create anappropriate degree of tension on the strip of paper as it is being setup to form a barrier, herein designated by the letter B, the supportingshaft has its outer portion slidably extending through an aperture l2 inthe beam and is surrounded by an expansion coil spring I3 which rests onthe beam and is held on the shaft by a washer and adjustment nut l4.

Although the implement is herein shown as being devoid of means'forpulling thesame, it is within the purview of this invention to attach itto any well known tractor or other suitable means whereby operationthereof is ensured.

With this invention fully described, it is manifest that a new and novelmethod of preventing crawling pests from attacking planted fields,herein indicated by the letter F, is provided and,

through the simplicity of the implement ernployed in practicing themethod, the cost of setting the barrier up will be reasonable.

Having thus described my invention what I claim and desire to protect byLetters Patent is:

A machine for erecting a barrier in planted fields, comprising a beamhaving its forward end downwardly directed, obtusely disposed axlesformed on opposite sides of the rear end of the beam, a downwardlyextending arm formed on the beam adjacent its rear end and havingforwardly diverging members formed on its lower end, a plow sharesecured to the forward end of beam, forwardly diverging blades securedto the aforesaid members with their outer ends extend ing beyond theouter ends of the aforesaid plow and their inner ends disposed in spacedrelation equal to the amount of dirt to be piled in a mound to the rearthereof, a roll of barrier material suspended beneath the beam midwaybetween the aforesaid plow and blades, means frictionally retaining theroll against undue winding action, I

said barrier material having its free end disposed between the bladesandpacking wheels journalled 0n the aforesaid axles to the rear of theblades. HAROLD F. MILLARD.
